Change Your Vacuum Pump Oil Frequently

Clean oil is important to achieve peak performance from your vacuum pump.  When your oil is contaminated, it reduces your vacuum pump's ability to remove moisture from a system.  You should change the vacuum pump oil frequently and always if…

1. You have just evacuated a system that you suspect is contaminated with moisture.

2. You have just evacuated a system that had a compressor burnout.

3. Your oil looks "cloudy" or "milky".

4. Your vacuum pump will not pull to the factory rated micron range when blanked off to an electronic thermistor vacuum gauge.
